Garth, thank you for the valuable explanation. I am wondering if we (the QGS community) should put this information somewhere to make it easily findable. We are currently in the process of redesigning the QGIS website (which includes links to the downloads for various operating systems).

Re: [Qgis-user] Using QGIS Server python API from system's default Python
Probably not the answer you are looking for but I strongly recommend you to use Linux for development and deployment (a virtual machine will work just fine): it will make your developer life much easier. We (https://github.com/g3w-suite/g3w-admin) have a Django-based application with QGIS API embedded, it works very well and I can recommend that approach. Kind regards.

Re: [Qgis-user] QGIS Server and Active Directory
Hi, not out of the box, but you might be able to develop a Python server plugin to implement custom authorization/authentication for the server. A few examples are available here: https://github.com/elpaso/qgis3-server-vagrant/tree/master/resources/web/plugins see httpbasic for example.

Re: [Qgis-user] Hello, new to QGIS
Hi, you have several options: you can store the QGIS project on a remote postgres DB and provided that the layer's data is also stored in a remote accessible DB you should be ready to go. If the data are stored on disk, you'll have to transfer them to the server in order to have them accessible on the server. Of course if you have other filesystem-based assets used by your project (icons, svgs etc.) you need to transfer them as well, keeping paths relative to the project path will make everything easier in that regard. If you don't want/can store the project in the remote postgres DB you can transfer the project and all other filesystem-based assets to the server.

Re: [Qgis-user] QGIS project templates and PostGIS connections
Hi Frank, you can safely use a custom authentication ID for the connection (choose something easy to type), then instruct your users to create an authentication configuration with the same ID but with their own credentials. This could be automated at the company level with a custom python init script, you can even place that on a network folder for easy access from sys admins. There used to be some examples around back from Boundless times, probably a little old but you can get the idea. https://boundless-desktop.readthedocs.io/en/latest/system_admins/init_scripts.html#add-an-authentication-configuration Hope this helps.

Re: [Qgis-user] Configuring QGIS server on Ubuntu 20.4
Hi, I'm sorry to hear that: we have even recently spent a considerable amount of time (and money, because it was financed with a grant) to rewrite the QGIS Server documentation with detailed information about deployment [1], we have clearly missed the goal if you couldn't find what you needed in these pages. It would be useful to know what exactly were your problems and what did you try to do. A common problem with server deployments is that there are multiple ways of doing things, it really depends on what you need, for example we are now commonly using docker containers (there are many out there that provide a QGIS Server working installation almost without the need to manually configure anything). Also, I tend to use nginx, but apache is totally fine too.

The authentication manager API is on purpose not complete: we didn't want a malicious python plugin to be able to access and disclose the credentials, however many functionality are exposed, I didn't check if all you need is actually available in the API but my gut feeling is that it is. It might be tricky to define the inactivity period though, web services typically use temporary connections and they may require to retrieve the credentials after some time when further data is requested from the server.

Re: [Qgis-user] Best practice, database vs WFS
Hi Paul, if you want to share geodata within your organization on a private network a database is the best solution: faster and simpler. The constraint is that you will need an application (like QGIS) to access your data.. WFS is a web service standard for interoperability, it is ideal for sharing data on the internet over HTTP, there is no need for a particular application to use the service: any HTTP client is able to do that.

If yes, it has nothing to do with Azure, it's cross-built in a Linux Docker container using using github workflows and it has some limitations (no Python is the most important one) but it's useful for testing QGIS core/GUI changes if you don't need Python.

Hi Jan,
There are many possible approaches to plugin testing, one of the most
interesting IMO is to use the testing docker which allows you to run
the tests inside a real QGIS instance and not a mocked one.
You can find examples of this setup in
https://github.com/inasafe/inasafe/blob/develop/.travis.yml and there
is some documentation in
https://github.com/qgis/QGIS/tree/master/.docker#running-unit-tests-inside-qgis
Hope this helps.

What I was trying to say is that you can create a project with (say) one PG layer that required your credentials (user "cliff") to be created but you want other users (user "alice") to be able to access the layer with her own credentials. You can create an authentication configuration and set its authid to some easy to share value (you have 7 chars if I remember correctly), then you will store your credentials in your authentication DB for that authid and "alice" will store her credentials in her own authentication DB using the same authid. Note that "alice" credentials are different from "cliffs" credentials, the authentication DB is also different (unless they are using the same machine and the same OS account and the same user profile), the only thing that is equal is the authentication configuration id. The thing is that you don't share the authentication DB, you share the authid 7 digits code only an the other users will use their own credentials.

Re: [Qgis-user] Save projects to DB without creator's permissions
Maybe all that you need is in the QHIS auth system is https://docs.qgis.org/3.10/en/docs/user_manual/auth_system/auth_workflows.html#changing-authentication-config-id The master password can be stored in the operating system wallet so that the user will not need to type his password.

The idea behind that development is that we are now able to automatically restore relations (and automatically search and load related layers) when a layer is loaded (or restored if it was a "bad layer") if the associated style uses a relation (i.e. the style uses a form that requires a relation, such as relation-reference, but value-relation also triggers automatic loading). Coming to your question: it should work, given that the related layers can be found. Layers are searched by id, then name and a few providers (postgres) can also automatically scan for the tables with the same name in the "current" schema and in other schemas of the same DB of the original layer (the one stored in the relation information in the style). You can have a look to the PRs for further details: https://github.com/qgis/QGIS/pull/33283 https://github.com/qgis/QGIS/pull/33103 https://github.com/qgis/QGIS/pull/32487 Hope this helps. -- Alessandro Pasotti QCooperative: www.qcooperative.net ItOpen: www.itopen.it ___ Qgis-user mailing list Qgis-user@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user

This won't work with rasters, you need to create a QgsRasterLayer, not
a vector one.
Coming to PG rasters, in QGIS 3.12 there are two providers that
support PG rasters:
- GDAL data provider
- native "postgresraster" data provider
GDAL data source uri uses the well known good old syntax to connect to
the raster (you can also test the connection from the command line
with "gdalinfo ").
The "postgresraster" provider is totally new in 3.12 and you can have
a look to the tests for PyQGIS use cases:
https://github.com/qgis/QGIS/blob/master/tests/src/python/test_provider_postgresraster.py#L82
Hope this helps.

Re: [Qgis-user] User setup for PostGres/PostGis use with QGIS
Note that there is a little trick that might make things easier: suppose you want to share a QGS project within an organization, by using the QGIS authentication database you can create an authentication configuration with a know ID (the usually automatic 7 characters ID) and share the project withing your organization using that authentication configuration to access the server, to load the project (and to connect to the server) all what a user would need to do is to create an authentication configuration with the same ID (but with his/her own credentials). We happily tested it with PKI user certificates on a postgis backend.

But notice that there is actually a difference: all the debug info goes to stderr, and the "listening" message goes to stdout. You can actually silence all QGIS server internal debugging and logging info by redirecting stderr to a file or /dev/null, you will get only the output from the application which goes to stdout.

No: that's not correct. qgis_mapserver binary is NOT a CGI module, it is a full HTTP (development) server. It listens on port 8000 by default (it should print it on stdout when it starts).

Re: [Qgis-user] bug in 3.10.2 (after upgrading from 3.10.1) with NULL being lost in PostGIS
Hi Jason, the quickest way to test current master for your case is to unzip the latest build artifact for windows 64bits (it's a zip inside a zip) on your PC and launch the qgis.exe binary you find inside. No installation is required and it's completely standalone, there is no Python but you don't need it for your test case. On every commit the artifact is automatically built: https://github.com/qgis/QGIS/actions?query=workflow%3A%22Windows+cross+build+with+MXE%22 The patches are very recent and they will be backported to 3.10 but I'll do that later this week. Let me know how it goes.

If I'm not wrong it's documented in the tooltip when you add/edit the URL.

But if I understand correctly what you were trying to do I'm afraid there is not a solution: the concept of "relative path" means relative to the project's storage path but that path does not make any sense in case of a POSTGRES storage (because POSTGRES is not a local filesystem-based DB in the same sense as GPKG or SPATIALITE are), so your file-system based asset paths are not (and cannot be) converted to relative paths because there is no project path we can relate to. This makes portability an issue if the project has filesystem-based layers (rasters in your case). There is no solution I'm aware of, storing rasters into PG is also not a viable option at the moment because support is currently buggy (see: https://github.com/qgis/QGIS/issues/30392).

Re: [Qgis-user] Loading non-spatial JSON using Python
Hi,
that doesn't look valid GeoJSON to me, you have no other options than
transforming the JSON to valid GeoJSON (or to any other format recognized
by QGIS ogr provider), or you can create a vector layer from scratches and
and add the individual features in a loop, it largely depends on what you
need to do next with those data.
Both approaches require a bit of programming.

Re: [Qgis-user] banging my head against the QGIS wall
You can try with python, and call it interactively. Also increase the logging level and if you can access a debug build set QGIS debug on.
